How To Make Amazing Stable RC Trainer Airplane With Handmade RC. Long Flight Time

How to make a model airplane that can fly very stable with Handmade remote control.
It is a model that is especially suitable for beginners. The fact that it is very stable, can take off from a short distance and provides a long flight time makes it a good trainer model. And it is relatively low cost…
It has a long flight time as it can fly at very low speeds with a small engine power. It can fly at a stable and reasonable speed, usually in the 32% – 45% gas range.
I performed the flight tests (3S) with 11.1V Lipo. But this model (2S) can also fly with 7.4V Lipo.

Wing span: 109 cm (42.91 inc)
Flight weight: About 675 gr
Center of gravity: 4.9-5.5cm from the front of the wing

In the video,
I showed 3 alternatives for the landing gear. The one I use is the 3D printed one. But any landing gear weighing less than 50gr and having similar dimensions can be used. 2.5mm thick steel wire can be used for a handmade landing gear. The link of the 3D landing gear I designed is below.

For this model, I used the 8-channel handmade remote control, the video of which I published before. Of course, only 4 channels are enough for a trainer plane. It provided good and stable control for this type of model. I had no control problems during the flight.
If you do not want to use a handmade remote control, you can fly this model with any 4 channel or higher remote control.
